whereby lb, ant is conveyed through one or mm'c apertures in' the pad to the slnrlting supported i lilfiernatively, rad ol int rposmg u grooved bearing pad between ,achlower abutment member and the lower front roller halting two or more anti-friction rollers, whereof-tho a-rbors may be .ri'iounted in. ball boari 's ii desired may be carried by each low r abutment member and be drawn into contact with the lower front roller shaft by the spring-controlled hanger bolt.

In order to enable the weighting pressure of all the spring-controlled hanger bolts to be relieved sinuiltancously, one of the following alternative means may be adopted;

For example each of the aforesaid bean Eng pads may, at its underside, be formed. integrallywith a tubular projection adapted to telescope into a corresponding housing, formed on or larried by each. lower abutand having within it a plunger or piston between the upper surface of which and the under surface of the bearing pad spring confined; and below said plung r or piston there may be articulated a rocking lever whereof the upper end is formed with a cam which contacts with the underside of said plunger or piston and whereotthe o ,osite or lower end is slotted and engages a in carried by a longitudinally movable rod adapted to y be displaced by screw, worm gear or other known means.

()r instead of the arrangement just referred to, thespr' 1;; may be located between the butterfly nut and hooked block on the hanger bolt itself, and the cam at the upper end of the articulated rocking lever may engage a projection depending from the bearing pad; the housing being omitted from the lower abutment member which may be constructed with bearings for an arbor upon which the rockin lever may be mounted.

Alternatively, the bearing pad may be supported by a seatiue block upon which is I projecting log opposite to which a, similar leg extemls from said seating block, and between said two legs there may be accommodutml the bzall-end one of a series of arms carried by a continuous shaft and embracing one or a series of eccentrics or cams formed on or borne by said shaft whereby said be l-endedarm may be caused to move nwardly of the two downwardlv projecting 7 corresponding front roller.

legs which are at an inclination to one another. Y

In addition to the aforesaid means for re leasing and rcstorin thepressure on all the rollers simultaneously, indi .idual pressureadjustment of the hanger bolts can also be effected by means of the usual butterfly or similar nuts carried atthe upper ends of the bolts.

The invention will not be way of example wi h reference to the accompanying drawings. in which Figurel is a vertical section of portion of the upper part of a machine frame, showing the invention applied to theupper and 1 Figure 2 detail rearview of partof the mechanism described by Figure 1.

Figure dis a view similar to Fi ur 1 showing a modified form of the mechanism illustrated therein; Figure l is det 7 view of part of the mechanism of 1 Figure is also another view sir; Figure 1, and showing a further alts means for releasing the spring weigl 1 are the upper front roliersand the lower front rollers of a spinning frtuae, the rollers 1 being mounted in pairs on are bors 3 supported by the usual brackets *1, and the rollers 2 being carried by a continuous shaft 5. V r

Along each side of the machine there is arranged, bet-ween each successive pair of up per front rollers l a hanger bolt 6 supporting a hook-shaped upper abutment member Tbearing on the upper front roller arbor 3 and having in Figures 3 and 5 a spring 8 confined between it and a butterfly nut 9 on the screw-threaded upper end of the hanger bolt 6.

The lower end of each hanger bolt 6 is hooked and takes intoithe eye 10 of a lower abutment member 11 which accommodates a bearing pad 13, of brass'or other suitable material, interposed betweensaid abutment 'member 11 and the lower front roller shaftlar housing 11 integral with each lower abutment member 11', and within said housing 11" is located a piston or plunger 11 between the upper face of which and the bearing pad 13 there is confined a spring 11;

The bottom of the housing 11 is pro vided with a diametrical aperture'through which there projects the upper end of a. rocking lever 15 articulated by a pin 15 mounted in appropriate bearings transversely of the bottom of housing 11?, and said rocking lever 15 formed at its head with a cam 15" adapted to contact with he lower face of the piston or plunger 11".

Each lower abutment member 11 is therei an individual actuator mecha isln. A forked bracket the like 11 r insthe movement.

The outer end of each rocking lever 15 is slotted at 15 k ried by a longitudinally movable rod 16 adapted to be displaced by any suitable means (not shown) when it is desired, to actuat the 'pressure-relieving aoparatus such actuation sh ing the rocking lever 15 from the position shownin full lines in Figure 2 into m position shown in dotted lines in the same i'igure, and the effect being to withdraw the nose of the cam 15 from contact with the plunger 11 thereby relieving or reducing the pressurc o'ericd by the spring 11 upon the bearing pad 13.

Obviously, on each side of the machine there is'a 16 which is common to the whole series of hanger boltsG on that side. Instead oft-he above described actuator mechanism, each bearing pad 13 may be formed, as shown in Figures 3 and 1, a cylindricaldependin projection 13- ex ending into the apertured and lifurcated cnd'll r of the lower abutment member 11 here it is engaged by the cam 15*; the -ocking lever 15 androd 16 being employed .s described al eady.

'Figure 2 illustrates a further alternative construction of pressure relieving mechanism, and in this case each bearing pad 13 issupported by a seating bloclr 17 upon which the lower abutn'ient member 11 mounted pivotally at 17 Fromsaid seating block 17 there extends a downwardly projecting leg 17 and the lower abutment member, 11 is extended at 11 alongside said leg 1'7 which is inclined slightly to the block from which it springs; and between members 11 and 17 there is accommodated the ball-end 18 of one of a series of arms 18 each being formed at its base 18 to embrace a cam 19 carried by a continuous shaft 20. V

The shaft 20 is adapted to be rotated by any suitable means in order to project the ball-end 18? between members 11 and 17" to move the extension 11 angularly and thereby pull downwardly the hanger bolt 6 when it is desired to relieve the pressure weighting. r

It will'be observed that in all the three constructions illustrated in Figures 1, 3, and 5 the action of the pressure-relievingmeans does not tend to disturb the direction of the housing- 11 from lateral pressure-Weighting force applied to the front rollers.

It will also be observed that should any wear occur in the bearing pads the align ment of the lower front roller shafting is not affected thereby,and that by the :bllb ployment of these pads or their equivalent the bearing area presented to said shafting is considerably increased.

hat we claim 1s F 1. Spring-weighting means for the front rollers of'spinning, twisting, roving and drawing said lower front rollers towards said upper front rollers, a series of actuator mechanisms each of which co-acts with one of said series of spring-controlled pressure devices, a longitudinal operating member operatively with each of said series of actuator mechanisms to enable same to release all said spring-controlled pressure devices simultaneously.
